A simple message of love writ large

CHICAGO -- When Shari Hart was diagnosed with leukemia last week, her 14-year-old son, Will, sent her a simple greeting.

"HI MOM," he wrote over the weekend, with a smiley face inside the "O."

Where he wrote his message was anything but simple.

 It appeared in giant letters in the snow on the roof of the parking garage across the street from his mother's room at Rush University Medical Center, reports CBS Chicago. Later, with help from his father, he added, "GOD BLESS U."  “Anyone who came in the room, I said, ‘Look what my son did,’" Shari Hart, 48, told CBS Chicago. "It was such a proud thing."

Hart is at the hospital for a month, receiving chemotherapy for acute myeloid leukemia. She said she could see her son and husband on the roof, waving and blowing her kisses, as they added the last three words.
 “It was just a true blessing, but I realized soon it wasn’t just for me," she said. "You know, it was really everyone on this side of the building could see it. So it became a lot bigger, a lot quicker.”

Angela Washek, a nurse at the surgical hospital's ICU, noticed Will’s message — visible to dozens of rooms at the hospital — very early Sunday morning.

Each letter is about two car-lengths long, she said.

 “It was really heartfelt," Washek said. "It was a lot of effort and it was really cold that night.”

 Shari Hart said that the message gave her joy.

So when you’re feeling a little low, just some simple words, ‘God bless you,’ made me cry," she said.
